System Components Configuration

Radio Connections



To install the radio and its KCT-19 cable:

Follow the directions in the Kenwood installation manual.

Plug connector E on the KCT-19 cable into CN4 on the radio PCB.

Radio Interface Configuration

Configuring the radio interface consists of setting jumpers inside the product if necessary.
Most of the jumpers can be left in their default settings. The configurable jumpers and
their functions are described in

Table 1

Figure 5

shows the locations of the jumpers.

Table 1. Configuration Jumpers in the Radio Interface (702-0006)

Jumper

Purpose

Positions

JP7 Data

Polarity

This jumper selects the data polarity. For normal
use, it should be left in position A.

A – Normal
B - Inverted

JP8 Data

Termination

This jumper should be set based on the number of
remotes connected to the radio interface.

A -

1 - 5 Remotes

B -

6 - 10 Remotes

C -

11 - 15 Remotes

OUT - 16 - 25 Remotes

JP19 Data

Loopback

This jumper loops the data back during self-tests.
It must be in position A for normal operation.

A – Normal
B - Test Mode

JP21 Test

This jumper is used to initiate self-tests. It must be
in position A for normal operation.

A – Normal
B - Test Mode
